A couple of months ago the skin of my penis began itching, mostly at the tip. I got tested for stds and herpes and all of the results were negative. The doctor advised me to try anti-fungal cream. I used that for two weeks and the itching didn't go away. Since it's not an std, herpes or a fungus I have no clue what it could be, but I would really like for the itching to stop. Any suggestions would be appreciated.
